Specification of Letters Patent. Patented June 29, 1920.

Application led July 8, 1914. Serial No. 849,791.

To all whom t may concern.' v

Be it known that I, PERRY BROWN, a citizen of the United States, and a resident of Coraopolis, in the county of Allegheny and State of Pennsylvania, vhave invented certain new and useful Improvements in Draft- Rigging, of which the following 4is a specification. j

This invention relates to improvements in draft riggings and one of the objects of the invention is to simplify the construction and also to provide means for connecting the shank of the coupler to the members which support the cushioning means in such a manner that the sills and the shank of the draw bar do not need to be slotted for the reception of any horizontal bars -passing through the same, though horizontal bars may be employed if preferred.

My invention consists inthe construction and arrangementof parts hereinafter more fully described and then definitely claimed.

In the drawings accompanying and forming part hereof and which represent the preferable, though not necessary, vembodiment of my invention:

Figure lis a bottom plan view of a rigging made in accordance with my invention; I y

` Fig. 2 is a vertical central section taken through the line aa of Fig. 1;

Fig. 8 is a horizontal section;

Fig. 4 is a detail showing the method of connecting the shank of the draw bar' with the rigging. c

Fig. 5 is a perspective View of one of the side bars detached; j

Fig. 6 is a perspective view of one of the fiollowers detached;

Fig. 7 is a horizontal section of my riggingwitli a slight modification;

Fig. 8 is a vertical central section through the line 5*?) of Fig. 7.

Referring now'to the details of thedrawings by numerals: 1 designates the end sill of a car and 2 and 3 the intermediate sills.

The ordinary couplerV or draw har `has its shank 4 provided with ribs or shoulders 5 on all of its sides.- VSaid shank is located between said intermediate sillsl 2 and 3 and` is connected in lthe manner hereinafter described with a `pair of side bars 6 and 7 which form a means of' supporting` the springs or other cushioning means. On the interior face of each of the longitudinal sills 2 and 3 I secure, as by riveting, abutment blocks 10 and 12. These abutment blocksmay be riveted directly to the longitudinal sills 2 and 8 as villustrated in Fig. 3, or angle irons as 14 and 16 in Fig. 7 may be interposed between the upper parts of the abutments 10 and 12 and the sills 2 and 3, as illustrated in Figs. 7 and 8. When the angle irons 14 and 16 are employed, it will be obvious that the angle irons form a means of connecting the front abutmentblocks 10 with the rear abutment blocks 12, see Fig. 7. The angle irons do not extend from the top to the bottom of the abutment blocks but only about one-third of the way down as illustrated in Fig. 8.

Referring again to the side bars 6 and 7, it will be observed, see particularly Fig. 5,

, that each side bar has a shoulder 2O at its 26, each side bar is formed with a recess ofY the peculiar shape shown in Fig. 5, this recess having an opening 29 leading into a second recess 30, the latter being dove tail in shape as shown` in Fig. 4.V This recess is designed to have a connecting bar 32 with dove tail ends 84 inserted through the opening 29 and up into the dove tail recess 30. After the connecting bar 32is located in its recess a locking bar 86 is'inserted through the opening 29 until it is immediately under the connecting bar 32 when acotter 88 may be inserted through perforations in lugs 42 and 40 projecting respectively from the connecting bar 32 and its locking bar 36, as

.shown in Figs. 1 and 2. The connecting bar 32 1s designed to pass underneath the'sha'nk 28 and 32 but upon a pull the draw bar will, through its ribs or shoulders 5 draw upon'the aforesaid bars 28 and 32 and pull said bars forward and thereby likewise move forward the side bars 6 and 7 to compress the springs in a manner readily understood by those familiar with draft riggings.

' The side bars 6 and 7 have been referred to as having longitudinal slots 24. Followers 50 and 52 are provided which are preferably of the shape shown in Fig. 6, each follower having a pair of lugs 54 projecting ony opposite sides thereof, these lugs being adapted to project through the slots 24 of the side bars 6 and 7. l/Vhen the two followers 50 and 52 are assembled, the usual cushioning springs 56 are located between them, the followers having bosses 58 to centerr the springs and flanges 60 at the top and bottom to inelose the outer portions of the springs, as illustrated in pFig. 2. The lugs 54 of each follower' are connected by means of a web 62 as illustrated in Fig. 6 and they webs of the two followers 50 and 52 project just the proper distance to contact witheach other when the springs are compressed to their capacity, thus prevent ing the springs from being crowded. When the parts are assembled, the shank 4 of the draw bar normally rests against the front follower 50 while the rear follower' 52 abuts against abutments 22 hereinbefore referred to as formed on the side bars 6 and 7. T he side'lugs 54 projecting from the rear follower 52, as before stated, project through the slot 24 in the side bars 6 and 7 and in the normal position these lugs 54 abut against the abutment blocks`12 riveted to the longitudinal sills 2 and 3. These abutment blocks 12 are each provided with a second abutment 74 (Fig. to receive the Vend thrust from the side bars 6 and 7 .when

side bars 6 and 7 are further provided with two sets of lugs 8O and 82, the lugs 82 being located in justthe proper position to project against the abutment blocks 12 and the lugs 80 being in the position to contact with the abutment blocks 10 when the draw bar is pulled forward and the springs compressed to their fullv capacity. Each of the side bars 6 and 7 is furthermore provided with a lug 90 (Fig. 5) which is adapted to project over the shank ofthe draw bar and maintain the parts in their proper relative positions.

The parts being formed as above described may be'assembled as follows: The two followers 50` and 52 first have their appropriate springs inserted between them and are compressed to the desired extent by kany suitable device, ,Then the side bar 6 lis placed in lowers 50 andl 52v and the springs, together with the horizontal bar 28, are now inserted between the longitudinal sills 2 and 3, the

parts being shoved up underneath the sills.

After these parts have been placed in position between the sills, the draw bar is placed in position so that the rib or shoulder 5 on the upper part of the shank ofthe draw bar fits behind thehorizontal 'bar 28 connecting the forward ends of the side bars 6 aI1d7. The carry bar 9U may now be placed in position and then the dove-tail horizontal bar 32 is inserted through the opening 29 and into its dove-tail recess 30 in the side bars 6 and 7. After this is donc, the locking plate 30 is inserted under the connectingbar 32, and the two secured together by the cotter 38. The rigging is now entirely assembled. If it is desired to support the rear end of the rigging a horizontal v carry-iron 92 may be secured to the under side of the sills'2 and 3 but this is preferably placed in position before the draw bar is secured to the side bars 6 and 7 L I believe the operation of my device will be easily understood by those skilled in the art, but it may not be amiss toy state that on an impact the shank of the `draw bar shoves the front-follower 50to the rear until the webs 62 of the opposing followers contact, when the springs will be compressed to their capacity, the rear follower 52 being sustained by the side bars 6 and 7, and the side bars 6 and 7 abutting'against the abutments 12 and 74 as clearly seen in Y IFig. 3. When the springs are compressed to their capacity on an impact, the lugs 82' cast on the outside of the side bars 6 and 7 contact with the abutment blocks 12, so that the load is sustained at a number: of

points, one where the side bars abut against the abutments 74. a second where the follower lugs 54 abut against the abutment blocks 12, and a third where the lugs 82 abut against said blocks 12. On a pull, the ribs or; shoulders 5 of the shank of the draw bar engage the abutments 20 on the, forward ends of the side bars 6 and 7 and also the horizontal .bars 28 and 32, and as the draw bar is moved forward the sidev bars 6 and 7 are likewise moved forward.. It will be seen from an inspection of the drawings that the front follower 50 can notmove forward Vas its lugs 54 strike againstthe abutmentfront follower 50 in a manner well understood. When the springs are compressed to their capacity, the lugs 8OV on the outside of the side bars 6 and 7 contact with abutments l0, these parts being so proportioned that they will come together at the same time the webs 62 will contact to prevent the springs from'crowding. Y

I desire to call particular attention tothe fact that the side bars 6 and 7 are so related with the followers 50 and V52 and their.

springs, that all vthese parts will hold themselves together while being assembled. In other words, when the side bars 6 and 7 have the followers and Vsprings placed between them, the springs will forcethe followers away from each other to the limit of the slots 24, and the projections 54 on the followers will co-act with the end walls of the slots 24 and all these parts will thereby be held together with sufficient firmness to enablethem to be inserted between the sills and their abutments without danger of the parts falling away from each other. Furthermore, when the bar 28 and the locking bar 32 are in position the front endsofthe side bars l6 and 7 are positively7 held to gether owing to the `dove-tail shape of the ends of the locking bar 32. With the use of this construction, I am enabled to connect my rigging to any M. C. B. draw bar. yIn case of repairs, itis necessary only to remove the bar 36 and the dove-tail bar 32, when the draw bar may be entirely removed from the rest of the rigging or the rest of thev rigging may be independently removed.

It will be obvious that changes and modifications may be made without departing from the spirit of my invention the scope of which is set forth by the appended claims. As an example, the abutment blocks l0 and l2 are preferably separate blocks riveted to the intermediate sills 2and 3. It will be obvious, however, that these, abutment blocks are the equivalent'of the ordinary cheek plates and where, in the following claims, the term abutments is used, I do not intend to be limited to the precise form of abutment blocks shown in my drawings.
